Safety Notes
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions
may result in electric shock, fire and/or serious
injury.
Save all safety warnings and instructions for future
reference.
The term “battery pack” used in these operating instructions,
irrespective of model, refers both to standard battery packs
(battery packs with holder on the bike frame) and to rack-type
battery packs (battery packs with holder in the rear rack/
carrier).
Make sure to not be distracted by the display of the
on-board computer.
If you do not focus exclusively on
the traffic, you risk being involved in an accident.
Read and observe the safety warnings and instructions
in all operating instructions of the eBike system and in
the operating instructions of your eBike.
